Detailed Description
The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The unlocking method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
With the popularization of intelligent electronic devices, the functions of electronic devices (such as mobile phones) are also expanded from the original communication functions to various aspects such as shopping, financial management, entertainment, learning, social contact and the like. It is precisely as electronic devices carry more and more roles that security and privacy protection of electronic devices is also more challenging. Cases that a payment application program is stolen and swiped when a mobile phone is stolen, chat records are leaked when the mobile phone is stolen, the cases that the mobile phone is loan-overtaken, privacy photos of a certain user are leaked and the like are frequently rare, and especially when the old and the minors use the electronic equipment to operate the related application programs, lawbreakers can take the opportunity to steal the electronic equipment. Currently, the following two schemes are mainly used to ensure the security and privacy of electronic devices.
In the first scheme: the screen saver password can be set for the electronic equipment, and the user can unlock the electronic equipment by inputting the correct screen saver password. However, in this scheme, if the setting of the screen saver password is too complicated, the user to which the electronic device belongs is easy to forget, and if the setting of the screen saver password is too simple, other users (e.g., some lawbreakers) may easily obtain the correct password to unlock the electronic device, so that the privacy information of the user to which the electronic device belongs is leaked. Moreover, after the electronic equipment is stolen, if the user does not turn off the debugging function in the electronic equipment, other users can also quickly crack the screen saver password according to the debugging function, and the screen saver password can be directly recovered to factory settings to bypass the screen saver password by a little violence, so that the privacy information of the user to which the electronic equipment belongs is acquired.
The second scheme is as follows: a screen saver password of the electronic device and a Personal Identification Number (PIN) of a Subscriber Identity Module (SIM) can be doubly encrypted to ensure the security of the electronic device. Specifically, in addition to setting a screen saver password in the security setting function, an electronic device manufacturer may further set a PIN password of the SIM card, that is, after the electronic device is powered off and restarted, the user may only be powered on by inputting the correct PIN password of the SIM card. However, in this scheme, the awareness that the user sets the PIN password for the SIM card of the electronic device is still weak, and the PIN password of the SIM card cannot completely block the private information from being leaked, and other users can retrieve the PIN password to unlock the electronic device by only needing the identification card information and the phone number corresponding to the SIM card to go to the business office to obtain the PIN Unlocking Key (PUK) password, so as to obtain the private information of the user to which the electronic device belongs.
In summary, the two schemes cannot reliably ensure the privacy information of the user to which the electronic device belongs, so that the security and confidentiality of the electronic device are poor.
In order to solve the above technical problem, in the embodiment of the present application, the first electronic device may pre-construct a key sharing system with at least one third electronic device, and determine a target electronic device for generating a key therefrom, such that the target electronic device generates and distributes a plurality of sub-keys, i.e. M sub-keys in the embodiments described below, to at least one third electronic device and the first electronic device, and, therefore, during the process of unlocking the first electronic device by the user, the first electronic device may obtain K first keys from at least one second electronic device (i.e., an electronic device of at least one third electronic device), where each second electronic device corresponds to at least one first key, and therefore, a target secret key is determined based on the K first secret keys and a second secret key prestored in the first electronic equipment, and the first electronic equipment is unlocked through the target secret key.
By the scheme, a distributed system is formed by a plurality of electronic devices with high confidence coefficient, each electronic device node in the distributed system becomes a sharer or a participant of a Shamir verifiable key sharing mechanism, when one of the electronic devices utilizes the acquired secret key for decryption, the correct password can be obtained only by sub-secret key combinations of most electronic device nodes in the distributed system, so that a user does not need to memorize various passwords or even memorize the passwords, the electronic equipment can be unlocked or the application program in the electronic equipment can be unlocked, the complexity of setting the unlocking password by the user is reduced, meanwhile, the safety of unlocking the electronic equipment by adopting the fixed password in the traditional scheme is greatly improved, and the risk that the privacy information of the user of the electronic equipment is revealed due to the fact that the secret key of the single electronic equipment is revealed is avoided.
In addition, when the SIM card in one electronic device is swapped out to another electronic device (the same manufacturer as the one electronic device), the Shamir verifiable key sharing interaction in the embodiment of the present application needs to be forced once, so that a series of interlocking risks caused by the theft of the SIM card can be further effectively prevented.
An unlocking method is provided in the embodiments of the present application, and fig. 1 shows a flowchart of the unlocking method provided in the embodiments of the present application, where the method may be applied to a first electronic device. As shown in fig. 1, an unlocking method provided by an embodiment of the present application may include steps 201 and 202 described below.
Step 201, under the condition that an unlocking interface of first electronic equipment is displayed, the first electronic equipment acquires K first keys from at least one second electronic equipment.
In this embodiment of the application, each second electronic device corresponds to at least one first key, and K is a positive integer.
In this embodiment of the application, if a user to which a first electronic device belongs wants to unlock the first electronic device, the user to which the first electronic device belongs may trigger the first electronic device to display an unlocking interface of the first electronic device, so that the first electronic device obtains K first keys from at least one second electronic device, each second electronic device corresponds to at least one first key, and thus, based on the K first keys and a second key pre-stored in the first electronic device, a target key is determined, and the first electronic device is unlocked through the target key.
Optionally, in this embodiment of the application, the unlocking interface may be an unlocking interface of a screen of the first electronic device, may also be an unlocking interface of some application programs in the first electronic device, and may also be any other possible unlocking interface in the first electronic device. The specific method can be determined according to actual use requirements, and the embodiment of the application is not limited.
Optionally, in this embodiment of the application, the user may perform a certain input to trigger the first electronic device to display an unlocking interface (e.g., a password input interface) of the first electronic device. In one implementation, a user may perform a screen unlocking operation to trigger the first electronic device to display an unlocking interface of a screen of the first electronic device, for example, the unlocking interface after the first electronic device is turned on, or the unlocking interface when the first electronic device enters a desktop of the first electronic device; in another implementation, when a user logs in a sensitive application (e.g., a privacy application), the first electronic device is triggered to display an unlocking interface of the sensitive application.
Optionally, in this embodiment of the application, the first electronic device may send a request message to the at least one second electronic device to request to acquire the first key of the at least one second electronic device, and receive K first keys sent by the at least one second electronic device; or, the first electronic device may also obtain the K first keys from the at least one second electronic device by other manners. The specific method can be determined according to actual use requirements, and the embodiment of the application is not limited.
Optionally, in this embodiment of the application, the "acquiring, by the first electronic device, the K first keys from the at least one second electronic device" may include steps a and b described below.
Step a, the first electronic device sends a request message to at least one second electronic device, wherein the request message is used for requesting to acquire a first key of the at least one second electronic device.
And step b, the first electronic equipment receives K first keys sent by at least one second electronic equipment.
Optionally, in this embodiment of the application, the K first keys may be sent by manually triggering an acknowledgement (that is, in an ultimate security mode) by a user to which each second electronic device in the at least one second electronic device belongs, or may be sent automatically by the at least one second electronic device (that is, in a non-triggered security mode). The specific method can be determined according to actual use requirements, and the embodiment of the application is not limited.
Optionally, in this embodiment of the application, each second electronic device may correspond to one first key, or correspond to multiple first keys.
Optionally, in this embodiment of the application, the first electronic device may obtain at least one first key from each second electronic device, respectively, to obtain K first keys.
Exemplarily, assuming that at least one second electronic device is 3 second electronic devices, such as the second electronic device 1, the second electronic device 2, and the second electronic device 3, the first electronic device may obtain 2 first keys from the second electronic device 1, 2 first keys from the second electronic device 2, and 1 first key from the second electronic device 3, thereby obtaining 5 first keys.
Alternatively, in the embodiment of the present application, the first key may be in any possible form of keys, such as letters, numbers, characters, character strings, maya characters, American Standard Code for Information Interchange (ASCII), and the like. The specific method can be determined according to actual use requirements, and the embodiment of the application is not limited.
Optionally, in this embodiment of the application, in a case that the first electronic device is in the secure area, the first electronic device may unlock the first electronic device by using a preset password (for example, a password preset by a user, or a password preset by the first electronic device), for example, the user may input a correct screensaver password (that is, a password matching the preset password) on the first electronic device to unlock the first electronic device. In the case that the first electronic device is in an insecure area (e.g., a dangerous area), the first electronic device may control the first electronic device to be in a key sharing unlocking mode to acquire a plurality of first keys when the first electronic device displays an unlocking interface, so as to unlock the first electronic device.
For example, as shown in fig. 2 (a), if the user of the first electronic device is at home and the first electronic device is in the secure area at this time, the first electronic device may unlock the first electronic device using a preset screen saver password (i.e., a conventional fixed password unlocking mode). As shown in fig. 2 (B), if the user to which the first electronic device belongs is out to visit, and the first electronic device is in the insecure area at this time, the first electronic device may control the first electronic device to be in the key sharing unlocking mode, so as to obtain a plurality of first keys when the first electronic device displays the unlocking interface, thereby unlocking the first electronic device.
It can be understood that the first electronic device can switch the unlocking mode corresponding to the first electronic device in real time according to the area where the first electronic device is located, so as to achieve the purpose of improving the safety and convenience of unlocking the first electronic device.
A specific method for acquiring K first keys by a first electronic device in an insecure area in the embodiment of the present application is exemplarily described below through two implementation manners.
Optionally, in an implementation manner of the embodiment of the present application, before "the first electronic device obtains K first keys from at least one second electronic device" in step 201, the unlocking method provided in the embodiment of the present application further includes step 301 described below. Step 201 may be specifically realized by step 201a described below.
Step 301, the first electronic device obtains a security level to which a location of the first electronic device belongs.
Optionally, in this embodiment of the application, the first electronic device may perform automatic area identification by using an artificial intelligence algorithm, so as to detect a security level to which a location of the first electronic device belongs.
Optionally, in this embodiment of the application, the first electronic device may label an unsafe place (for example, some dangerous areas that the user who the first electronic device belongs to frequently goes), and then train the dangerous area identification algorithm to obtain a dangerous area identification model, so that the first electronic device may determine, according to the dangerous area identification model and the relevant location information of the first electronic device, a safety level to which the location of the first electronic device belongs.
Optionally, in this embodiment of the application, the dangerous region identification algorithm may be a Gradient Boost Decision Tree (GBDT) algorithm, or may be any other possible region identification algorithm, which may be specifically determined according to actual use requirements, and this embodiment of the application is not limited.
Optionally, in this embodiment of the application, the first electronic device may input the relevant location information of the first electronic device into the dangerous area identification model to determine the security level to which the location of the first electronic device belongs.
Optionally, in this embodiment of the application, the information related to the location where the first electronic device is located may include location information where the first electronic device is located, gender information of a user around the location where the first electronic device is located, age information of the user around the location where the first electronic device is located, and the like. The specific method can be determined according to actual use requirements, and the embodiment of the application is not limited.
Optionally, in this embodiment of the application, the security level to which the location of the first electronic device belongs indicates a security degree of the location of the first electronic device. It is understood that the first electronic device may determine whether the first electronic device is in the safe area by acquiring the safety level to which the first electronic device is located.
Optionally, in the embodiment of the present application, the security level may be a numerical value, a percentage, or any other possible form of level. The specific method can be determined according to actual use requirements, and the embodiment of the application is not limited.
Step 201a, under the condition that the security level is within a preset level range, acquiring K first keys from at least one second electronic device.
Optionally, in this embodiment of the application, if the security level is within the preset level range, which indicates that the first electronic device is in an insecure area, it is necessary to control the first electronic device to be in the key sharing unlocking mode, that is, by acquiring keys of other electronic devices, the first electronic device and the other electronic devices jointly unlock the first electronic device.
Optionally, in this embodiment of the application, the preset level range may be a default level range of the first electronic device, or may be a level range preset by a user to which the first electronic device belongs.
It should be noted that the key sharing unlocking mode may be understood as an interactive key agreement performed by a plurality of electronic devices to unlock a certain electronic device more securely.
In the embodiment of the application, the first electronic device can adaptively judge the security level of the current position to identify whether the region is a secure region, and under the condition that the first electronic device is in an insecure region, the first electronic device can automatically switch the fixed password unlocking mode into the key sharing unlocking mode and acquire K first keys from at least one second electronic device, so that the risk of disclosure of privacy information of a user to which the electronic device belongs due to disclosure of the keys of the single electronic device is avoided, a series of interlocking risks caused after the passwords are stolen are further effectively prevented, and the security and confidentiality of the electronic device are improved.
Optionally, in another implementation manner of the embodiment of the present application, before "the first electronic device obtains K first keys from at least one second electronic device" in step 201, the unlocking method provided in the embodiment of the present application further includes step 401 described below.

It should be noted that the voting method can be understood as follows: each third electronic device may select one third electronic device as a master electronic device, and when one third electronic device selects another third electronic device as the master electronic device, the number of votes of the another third electronic device is increased by one, so that at least one third electronic device and the first electronic device may determine the electronic device with the highest number of votes as the target electronic device according to the voting information. The manner of preempting can be understood as: each third electronic device can perform preemption, who preempts the preemption first and who is taken as the target electronic device, so that the third electronic device which sends the preemption message earliest can be determined as the target electronic device by at least one third electronic device and the first electronic device.
Optionally, in this embodiment of the application, after determining the target electronic device, the first electronic device may send a first message to the target electronic device, and the target electronic device may determine whether the first electronic device is in a safe area according to the location information of the first electronic device in the first message.
Optionally, in this embodiment of the application, the target electronic device may determine, according to the location information of the first electronic device, a security level to which a location of the first electronic device belongs, so as to determine whether the first electronic device is in a security area.

Optionally, in this embodiment of the application, the target electronic device may send a second message to the first electronic device to indicate that the first electronic device is in the key sharing unlocking mode, when it is determined that the first electronic device is in the insecure area.
Exemplarily, assuming that the at least one third electronic device includes a third electronic device 1, a third electronic device 2 and a third electronic device 3, and the third electronic device 1 is a target electronic device, in a case that the third electronic device 1 determines that the first electronic device is in the insecure area, the user to which the third electronic device 1 belongs may trigger the third electronic device 1 to send a second message to the first electronic device through an input to indicate that the first electronic device is in the key sharing unlocking mode.
It should be noted that, for the description of the key sharing unlocking mode, reference may be specifically made to the related description of step 201a in the foregoing embodiment, and details are not described here again.
In the embodiment of the application, the first electronic device may send the position information of the first electronic device to the target electronic device, so that the target electronic device determines whether the area where the first electronic device is located is a secure area according to the position information, and under the condition that the first electronic device is determined to be located in an insecure area, the target electronic device may send a message to the first electronic device, so that the first electronic device switches the fixed password unlocking mode to the key sharing unlocking mode according to the message, and obtains K first keys from at least one second electronic device, thereby avoiding a risk that the privacy information of a user to which the electronic device belongs is leaked due to the leakage of the keys of the single electronic device, further effectively preventing a series of linkage risks caused after the passwords are stolen, and thus improving the security and confidentiality of the electronic device.
Optionally, in this embodiment of the application, in an implementation manner, the first electronic device may autonomously generate a super key, encrypt the super key into a plurality of sub-keys, then store a part of the sub-keys in the plurality of sub-keys, and distribute, to at least one third electronic device associated with the first electronic device, the remaining sub-keys, except for the part of the sub-keys, in the plurality of sub-keys. In another implementation, the first electronic device may determine a target electronic device from at least one third electronic device associated with the first electronic device, and request the target electronic device to generate a secret key, and the target electronic device may generate a super key, encrypt the super key into a plurality of sub-keys, then save part of the sub-keys in the plurality of sub-keys, and distribute the rest of the plurality of sub-keys to the first electronic device and the rest of the at least one third electronic device.

Optionally, in this embodiment of the present application, the Shamir key sharing algorithm is represented by a binary number (k, n), where n represents that a plaintext s (i.e., a super key) is encrypted into n ciphertexts, and k represents that at least k ciphertexts must be owned at the same time to decrypt the plaintext.
For the super key s to be encrypted, k-1 random numbers a are arbitrarily taken in the finite group GF (P)1，a2，...，ak-1And make a0S, thereby constructing the following polynomial:
f(x)＝a0+a1x+a2x2+a3x3+……+ak-1xk-1mod(p)
for the above polynomial, any number n, i.e. x, is taken1，x2，…，Xk-1Respectively substituting the polynomials to obtain n key pairs:
f(x1)＝a0+a1x1+a2x1 2+a3x1 3+……+ak-1x1 k-1mod(p)
f(x2)＝a0+a1x2+a2x2 2+a3x2 3+……+ak-1x2 k-1mod(p)
f(x3)＝a0+a1x3+a2x3 2+a3x3 3+……+ak-1x3 k-1mod(p)
……
f(xn)＝a0+a1xn+a2xnn 2+a3xn 3+……+ak-1xn k-1mod(p)
